How do I choose the right power adapter for my device?
The laptop model is usually located on the bottom of the device. Read it and enter it into the shop's search engine.
e.g. Asus K53SV / HP Pavilion G6 / MacBook Pro 13 A1278
value of INPUT / OUTPUT
On the nameplate of the power supply, the voltage and current values are marked as OUTPUT, and on the bottom of the laptop the same parameters are marked as INPUT. Read some of them and enter them into the store's search engine, adding the brand of the device to them. Make sure the plug of the found power adapter is correct.
e.g. Asus 19V 4.74A / Dell 19.5V 4.62A / Lenovo 20V 3.25A.
I have a 65W PSU or can I use a 90W PSU?
With such small differences, it is acceptable. However, we must remember to use power supplies with higher power, not less, because at lower power the laptop may not work.
Is this power adapter suitable for my laptop?
It will be suitable for our laptop if the connector diameter meets the outer diameter specification, eg 5.5mm, and the output parameters are compatible. What are output parameters? It is the value of voltage[V] and current[A] given by the power supply for a laptop, eg 19V 4.74A.
Laptop power supply - what voltage?
When choosing a new power supply for your laptop, you should check the voltage of the charger - this parameter should match your original device.
HP Compaq laptops are popular due to their excellent value for money. However, as with any device of this type, they require the right power adapter to be fully functional. It is thanks to it that the device can always be charged and ready to work, hence consider buying a spare charger for HP laptop.
A laptop charger usually does not have an easy life. Frequent bending, trampling and tripping over the cable greatly accelerates the need to purchase a new model. If you own an HP Compaq laptop, you will find the right charger for your device in this category.
The HP charger will also come in handy if you frequently use your laptop in different locations. By purchasing an extra unit, you can ensure that the power adapter is always with you - in the car or the office for example.
If you're about to buy a charger, the number of options available may make you dizzy. With our helpful and intuitive search engine, you will quickly find a model with the appropriate parameters.
What should you look for? First, prepare the model designation of your charger. You may find this on your previous power adapter. Remember, however, that this only tells you the current rating - you also need the type of plug for a correct match.
The round plug is the most common. Its size depends on two numbers - the first is the diameter of the outer circumference, and the second - the inner circumference. In this category, we have gathered for you, chargers with as many as seven different types of plugs - you will certainly find among them a model to fit your device.
But what if you no longer have access to your previous power adapter? Then use our search engine. Just type in your laptop model, and you will get a list of all compatible chargers from our range in no time. You will find the model of your laptop on the internal nameplate underneath the battery.
What other parameters should you take into account? Check the voltage in volts (V) and the amperage (A) of the current that your laptop adapter supplies. The voltage should not differ by more than one volt from the value recommended by the manufacturer.
If you multiply the voltage and amperage by each other, you get the wattage of the charger in watts (W). Remember that the power of the charger should not be less than the recommended value. You can also use a more powerful charger without worry. This will put less strain on the power supply and keep it at a lower temperature.
If you are going to travel, consider the input parameters (INPUT). Check what voltage the chosen power supply is designed for. The European standard is 230 V. However, Japan uses 100 V and the Middle East 240 V. When choosing Green Cell power supplies, you won't have to worry about buying the wrong model - all accessories have an operating range of 100-240 volts.
You should also pay attention to cable length. Your working comfort depends on it. A long enough cord will allow you to use the device without the need for an extension cord. A short cable is an advantage if you often travel with your laptop and want it to take up as little space as possible.
